are spread over a larger area of the Earth's surface, so the light received is more indirect and of lower intensity. Between this effect and the shorter daylight hours, the axial tilt of the Earth accounts for most of the seasonal variation in climate in both hemispheres.

Elliptical Earth orbit

Compared to axial parallelism and axial tilt, other factors contribute little to seasonal temperature changes. The seasons are not the result of the variation in Earth's distance
